PROCESS OF MAKING WIRE.

SPECIFICATION forming part of Letters Patent No. 514,766, dated February13, 1894.

Application filed October 22, 1892. Serial No. 449,668. (No specimens.)

To all whom it may concern:

Be it known that I, BENJAMIN MOUNTAIN,

a subject of the Queen of Great Britain, residing at Castleford, in thecounty of York,'England, have invented certain new and usefulImprovements in the Manufacture of Wirenamely, a process for themanufacture of wire from metallic rings or hoops; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same.

Hitherto in the manufacture of wire it has been customary to cast themetal in'ingots or straight pieces which have been afterward reduced tothe requisite thickness by ordinary rolling and drawing; operations wellunderstood by those in the trade.

My invention has reference to a process for the manufacture'of wire frommetalic rings or hoops, whereby longer lengths of wire can be obtainedthan by the process above referred to, and at a reduced cost. And mysaid process consists in first casting the metal in ring or hoop form,then thinning the ring or hoop by rolling apparatus which reduces it inthickness while enlarging it in diameter, then cutting the ring or hoopup spirally by means of slitting or cutting up apparatus, and thenpassing the metal strip so produced through the ordinary wi-re drawingapparatus so that itis reduced to the requisite gage.

In the drawings, Figure 'l, is a sectional side view of apparatus forcasting the metal in ring or hoop form. Fig. 2, is a front 'elevation ofFig. 1, partly in section on the line or. a). of Fig. 1. Fig. 3, is anend elevation of apparatus for rolling the rings or hoops in the manneraforesaid. Figs. 3 and 4 are detail views hereinafter explained. Fig. 4,is a side elevation of Fig. 3. Fig. 5, is a front elevation of apparatusemployed for slitting or cutting up the rings or hoops combined withapparatus for reeling up the metal strip as it leaves the cutters whichaction also imparts motion to such cutters as hereinafter explained.Fig. 6, is a sectional side elevation of the slitting or cutting upapparatus shown in Fig. 5. Fig. 7 is an elevation of the wire drawinggage.

Figs. 1, and 2. Casting the metal in ring or hoop for-m.-A is arevolving mold (carried upon a shaft B through which it receives itsrotation) having a detachable face plate 0 which is secured to the saidmold by bolts D and cotters E, so that it can be readily taken off orsufficiently removed in order to take out the metal ring or hoop andreplaced for molding the next ring or hoop. F is aguide trough intowhich the molten metal (to which is added a little salt) is poured andfrom p which it runs into the mold through the opening G in the plate G.The mold is revolved at a speed of seven hundred revolutions per minute,the centrifugal force keeping the molten metal equally distributedaround the mold and quickly cooling it: Preparatory to pouring in themolten metal the mold is lined with ground charcoal and oil to preventsticking of the metal.

Figs. 3 and 4:. Rolling the ring or h00p.--. A is a frame upon which aremounted rollers B and C. The roller B (which is preferably of steel) isloose upon a fixed shaft D or a stud, and is employed for rolling oroperating' upon the inside of the ring or hoop B which is placed uponit. This roller B is hereinafter referred to as the interior roller. Theroller 0 is fixed upon the revolving or main shaft E" and operates uponthe outside of the ring or hoop, and is therefore hereinafter referredto as the exterior roller. The exterior roller is capable of adjustmentin the guides K so as to regulate its distance from the interior rolleras required by. the thickness of the ring or hoop being rolled, and toimpart the required rollingpres'sure by means of hydraulic ram Fconsisting of cylinder and piston as ordinary, the pressure imparted bythe said hydraulic ram F being removed when required, by means of asmaller or similar hydraulic ram G, also consisting of cylinder andpiston as ordinary, and commonly called a withdrawing ram. H are guideplates for holding or supporting the ring or hoop being rolled, so as tokeep such from slipping too much one way, and such guide plates arecapable of being adjusted bymeans of lever J and bevel gears L. M arecoupling boxes for joining the shaft E.

The mill is driven by means of engine or other shaft N upon which is apinion O which gears with a wheel P upon the main or revolving shaft E.

In Fig. 3 is shown a sectional view of the hydraulic cylinders andpistons of the rams F and G and connections. A is the piston, B thecylinder in which the said piston works and C the hydraulic collar,which is such as is used in Brahmahs press. This hydraulic collar is Ushaped, and made of leather. D is the withdrawing piston working incylinder E and coupled to piston A by link F G is the stuifing-box. IIis the inlet pipe. J the outlet pipe. These pipes are connected to aslide valve which consists of valve case K in which works the Valveslide L, which is worked up and down by means of screwed rod M (workingin a corresponding thread in the top N of the valve case K and having ahand wheel O In the position shown in the drawings the inlet pipe isopen and the outlet pipe closed. On screwing up the slide L the outletpipe is opened and the inlet pipe closed. Of course the inlet pipe iscon- 'nected to the accumulator from which the pressure is obtained.

In Fig. 4: is shown a plan of the mechanism for operating the guideplates H. H are the guide plates carried upon shafts H that areconnected by the bevel gears L and crossshaft H One of the said shafts Hhas engaged to it the weighted hand lever J. On depressing this lever Jthe guide plates II are raised out of action. When the leverJ is in itsnormal position, or not depressed, the guide plates H act in the manneralready explained to keep in place the ring or hoop that is beingrolled. B is the top roll and B the ring in section.

Figs. 5 and 6. Sl'itting or cutting up the ring or ho0p.-A is a framemounted upon which are horizontal shafts B and O free to revolve intheir bearings. The said shafts carry cutters D and E the top cutter Dbeing vertically adjustable, so as to regulate the cutting action, bymeans of handwheel F and screw Gr engaging with block H in which isjournaled one end of the shaft B The said cutters are secured betweenface plates J and back plates K the whole being bolted together. L areguide pulleyssecured upon brackets M bolted to or cast upon the frameA". N is a separate frame (or it may form part of the frame A mountedupon which 1s a horizontal shaft 0 receiving its motion from the engineby means of ordinary driving pulley fixed upon the said shaft. Thehorizontal shaft 0 has a bevel wheel P which gears with another bevelwheel R upon a vertical shaft S which carries a drum or cone T at itstop end and at its lower end revolves in a bush U secured upon a bracketor plate V fixed upon the machine or frame N The ring or hoop to beslitted or cut up is placed upon the lower cutter E (a portion of itsedge or surface having been first started or opened by means of a pairof strong shears, such as crocodile shears). Sufficient strip is thenstarted by the ordinary pulling in wire process to connect the ring orhoop with the revolving drum or cone T which draws the metal through thecutters, and by so doing causes them to revolve and the necessarycutting action is thus imparted so that the ring or hoop is convertedinto metal strips which are afterward passed through the ordinarydrawing apparatus to bring the strips to the required gage of wire.

The drawing of the metal strips into wire is accomplished in theordinary well known manner.

In Figs. 5 and 7 N" is the wire drawing gage carried in the frame N inwhich it is adjustable. The frame of the wire drawing gage is bolted orfastened upon the frame N as shown. The metal strip passes through thisgage and is thus drawn into wire that is wound on the drum '1 as shown.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is-- The process of manufacturing wire which consistsin first casting the metal in ring or hoop form, then thinning out thering or hoop by rolling it so that it is reduced in thickness andincreased in diameter, then spirally slitting or cutting the ring intostrips, and finally drawing the said metal strips into wire of therequired gage, substantially as described.
